I was born in 2911. My nickname is “Twenty Square” because I’m very fond of the “Royal Game of Ur”, an ancient game represented by two gameboards found on Earth, in the Royal Tombs of Ur in Iraq by Sir Leonard Woolley in the 1920s.

Someone calls me “Cumberlain”. It’s an old joke from high school. I maintain this nickname in some circuits, just to recall old timers.
